Hypoxia becoming more widespread along Baltic Sea coastline
Hypoxia (low levels of oxygen) is widespread in the coastal waters of the Baltic Sea, according to recently published research. The trend of increasing hypoxia since the 1950 is alarming, although improvements can be seen in some areas as a result of measures to reduce inputs of organic material. Download article (PDF)

Animal-pollinated crops provide essential nutrients for humans
Crop pollination is a vital ecosystem service, yet the numbers of animal pollinator species, such as bees, are in decline. Now, a team of German and American researchers have demonstrated how crops that provide the highest levels of vitamins and minerals essential to our diet globally depend heavily on animals for pollination.

High atmospheric CO2 levels stimulate GHG emissions from soil
Rising levels of atmospheric carbon dioxide (CO2) is likely to cause some soils to release large quantities of two potent greenhouse gases (GHGs), nitrous oxide and methane, according to a recent analysis. The results suggest that the contribution of soils and terrestrial ecosystems to slow climate change has been overestimated. Download article (PDF)

Wind power reduces environmental impacts of desalination plants
Desalination plants, powered by wind energy, offer the potential to produce freshwater using a renewable source of energy. A recent study has explored some of the challenges of integrating wind energy with desalination units, and suggests combining wind with other forms of renewable energy, or constructing a system that operates with variable energy input would help overcome problems with wind powered desalination.

Emissions from tropical deforestation neutralise large carbon sink
A new study suggests that, although the global terrestrial carbon sink remained relatively stable from 1990 to 2007, the effects of tropical forests were virtually neutral because CO2 emissions from deforestation offset their carbon sink. Download article (PDF)

What happens to chemical dispersants used in deepwater oil spills?
The Deepwater Horizon Oil Spill saw the first ever use of chemical dispersants to reduce the impacts of an oil spill at a deepwater level. A new study has investigated the fate of these dispersants in deepwater and concluded that they do not biodegrade well. Download article (PDF)

Titanium dioxide and zinc oxide nanoparticles restrict wheat growth
Nanoparticles (NPs) have unique physical and chemical properties, but their increasing use in technological innovations has raised concerns about possible risks to the environment and human health. A new Chinese study has assessed the effects of NPs on plants and ecosystems. The findings indicated that NPs restrict wheat growth and damage soil ecosystems, which may have implications for the environment, agricultural productivity and human health. Download article (PDF)

The central role of NGOs in sustainable fisheries
The growing influence of non-governmental organisations (NGOs) in the seafood industry means that they now play a central role in setting standards for sustainable fisheries. In a new study, researchers used the Dutch Good Fish Guide to illustrate how NGOs can efficiently engage consumers, industry, fishermen and government. Download article (PDF)
